Abstract: Instructors have frequently found that some content, such as mathematical formulae, chemistry laboratory experiments, and business practices, are unusually difficult for students to comprehend through text-centered approaches, and that this is especially so for online students. In response, instructor-made videos (IMVs) of three to 10 minutes in length on problematic topics or subject matter areas were produced for business, chemistry, and mathematics courses. The IMVs were intended to scaffold student learning. Initial findings revealed that multimodal IMVs involving the demonstration, illustration, and presentation of key terms, knowledge, skills, and resources can help students understand important procedures, structures, or mechanisms in previously problematic content. Simply stated, IMVs can have a positive impact on student learning.Volume 8, No. 4, December 2012, pp. 298-311HTML / PDF

A unique online parsing system that produces partial-credit scoring of students' constructed responses to mathematical questions is presented. The parser is the core of a free college readiness website in mathematics. The software generates immediate error analysis for each student response. The response is scored on a continuous scale, based on its overall correctness and the fraction of correct elements. The parser scoring was validated against human scoring of 207 real-world student responses (r = 0.91). Moreover, the software generates more consistent scores than teachers in some cases. The parser analysis of students' errors on 124 additional responses showed that the errors were factored into two groups: structural (possibly conceptual), and computational (could result from typographical errors). The two error groups explained 55% of students' scores variance (structural errors: 36%; computational errors: 19%). In contrast, these groups explained only 33% of the teacher score variance (structural: 18%; computational: 15%). There was a low agreement among teachers on error classification, and their classification was weakly correlated to the parser's error groups. Overall, the parser's total scoring closely matched human scoring, but the machine was found to surpass humans in systematically distinguishing between students' error patterns.

In this paper, we describe our introduction of anonymous online office hour sessions for mathematics courses and outline a number of ways in which these sessions are more effective than traditional office hours. Our study is based on our experience with conducting the sessions as well as on data from student surveys. Our sessions make use of the enVision communication software (freeware), which permits easy, real-time communication of complex mathematical ideas.

Many teachers whose backgrounds are not in statistics must teach statistical concepts. Non-statisticians face extra challenges in preparing for a statistics class, including uncertainty about content and pedagogy. This article addresses this challenge by suggesting the use of CAUSEweb, an online repository of statistics education resources. Methods are described to incorporate this resource into the planning and teaching of several difficult statistical concepts, including time series and hypothesis testing, using resources tailored to different application areas, such as biology, engineering, and chemistry.

Abstract This paper evaluates the issues and challenges associated with Hispanics financing higher education. In addition, the paper will analyze how various strategies such as self-advocacy skills training, financial aid informational programs, and early academic interventions in high school and junior high can positively influence Hispanic students’ educational attainment rates. The paper will synthesize how cultural and family expectations play major roles in Hispanic students’ college aspirations. Finally, the evaluation will reveal why variables such as poverty and financial/credit constraints are not the only overriding barriers to college aspirations, attrition rates, and degree completion rates for this group.

The patterns of variation within a molecular sequence data set result from the interplay between population genetic, molecular evolutionary and macroevolutionary processes—the standard purview of evolutionary biologists. Elucidating these patterns, particularly for large data sets, requires an understanding of the structure, assumptions and limitations of the algorithms used by bioinformatics software—the domain of mathematicians and computer scientists. As a result, bioinformatics often suffers a ‘two-culture’ problem because of the lack of broad overlapping expertise between these two groups. Collaboration among specialists in different fields has greatly mitigated this problem among active bioinformaticians. However, science education researchers report that much of bioinformatics education does little to bridge the cultural divide, the curriculum too focused on solving narrow problems (e.g. interpreting pre-built phylogenetic trees) rather than on exploring broader ones (e.g. exploring alternative phylogenetic strategies for different kinds of data sets). Herein, we present an introduction to the mathematics of tree enumeration, tree construction, split decomposition and sequence alignment. We also introduce off-line downloadable software tools developed by the BioQUEST Curriculum Consortium to help students learn how to interpret and critically evaluate the results of standard bioinformatics analyses.

Introduction The proportion of college and university presidents who are women continues to rise. However, while women are relatively well represented within community colleges, they are significantly underrepresented as presidents of four-year institutions, especially major research universities. Many reasons for this disparity have been suggested, one of which is the belief that conceptions and models of leadership generally exclude the unique strengths and leadership styles of women. From a review of the literature, this paper will identify the various leadership traits and behaviors that are believed to be the domain of women more than men. In addition, this paper will identify three popular models of higher education leadership and analyze the extent to which they do or do not apply to women leaders. According to Coughlin, Wingard, and Hollihan (2005), a major difference between domination and partnership models is not that the partnership model is hierarchy-free, as both models do consistently prove to require hierarchy chains of command. The difference between domination and partnership hierarchy models is that one is based in domination and the other is based in actualization (p. 29). Managing highly intelligent individuals in a learning organization can work more effectively by incorporating a hierarchy of actualization model rather than an authoritative, domination model. An actualization model supports relationships, respect, caring, and mutual benefit rather than models of management that identify winners and loser (p.29). A hierarchy of actualization leadership model is well suited to the specific traits and behaviors associated with how women lead others. Furthermore, this new “actualization” concept is fast becoming a leadership model that has been identified as successful in higher academia. Although women have participated and exceeded in the areas of scholarship and published work, more effort needs to be done with regard to leadership attainment at the highest levels of academia, especially within research institutions. According to Martin (1999), “when women become full members of the academy a new and improved academic culture might be forged” (p. 118). This paper will identify leadership models in higher education and describe which models are better suited to how women naturally lead others based upon the literate and will discuss why those models are important and necessary in the sector.
